SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 376,355, dated January 10, 17888.

' 4Application filed May 3, 1887.- Serial No. 2 .7,019. (Model.)

T all whom it may concern:

Beit known that we, FRANCIS M. VARE and GEORGE W. BENJAMIN, of North Bend, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in SealLocks, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure I is a perspective view of our car seal and lock; Figs. Il, III, and 1V, vertical sectional views showing the structure of thelocking devices and their operation iu the process of locking; Fig. V, a perspective view of the pa'wl for holding the bolt and boltseal, and Fig. Viaperspcctive viewof the lower end of the bolt.

The Object of this invention is to improve the device for which we made application for Letters Patent December 24, 1886, SerialNo. 222,437; and it consists in adapting certain features of that invention to a bolt-lock, and in using a sheetof metal as a seal, in which is a rectangular opening which is designed to be placed over a portion of the locleward, all of which will now be set forth in detail.

In the drawings, A represents the base on which various parts ofthe bolt are mounted. This base may be attached to either the door or the j amb. Centrally on this base is a staple, B, having a vertical aperture, through which the sliding bolt C passes. The slotted hasp D is placed over this staple, and when in position rests against the base A behind the vertical bolt C.

Near the upper end of the base A, and cast integrally therewith, is ahousing, E, through which is a vertical hole in line with the hole in the staple B, for the purpose of receiving the bolt C, the upper end of which bolt has a ring, C. A spring, F, located on top of the housing E, rests against the bolt, and the latter has a notch, (not shown,) so that when the bolt is raised toits highest point the spring will enter the notch and hold the bolt from falling back into the locking mechanism. The upper end of the bolt C is provided with one or more ribs, G, on its body, which correspond with suitable grooyes in the sides ofthe holes of the housing E and staple B, so as to prevent the bolt from turning. The'lower end of the bolt has a short projecting stem, H, which is preferably squared and made smaller than `D to the lock.

the main body of the bolt. The body of the bolt C has at its shoulder I two projecting ears, J, which extend over the upper end of the housing which contains'the lockingmechanism. The object of these ears is twofold-first, to afford a cap or covering for the slot in the housing below, and, second, to he used as stops to prevent the withdrawal of the bolt from the housing E. The staple B has in the walls of its aperture a groove, K, on each side, which permit the ears to pass up through said staple when it is desired to attach the slotted hasp The stem H is tapered at its lower end,and has on one side a notch, N, so as to form a hook, O.

The housing P, located on the lower end of the base A, contains the locking mechanism, which will now be described. The upper wall of the housing has a hole, Q. to receive the stem Hof the bolt C. The upper end of the housing has alvertical slot, R, across it, which sloteXtends down about one-third ofthelength of the housing. This slot is so located that theY point of the bolt-stem H passes down into the housing slightly to one side of it. Within Y the chamberformed Yby the housing is a peculiarly-formed pawl, S, having ou one side a portion, T, cut out of it, so that the stem H of the bolt O. will fit therein.4 The opposite side of this pawl has its upper corner cutaway, as shown at U. This pawl is mounted on the upper end of a spring or springs, V, the lower ends of which are secured to the bottom of the chamber in such a manner' that the pawl is free to move back and forth in the chamber directly below the opening Q, When the pawl S is in its normal position, the line of the slot passes centrally through it. Directly opposite the lower point of the pawl, on the side having the inclined or curved face, is a projecting point, WV, in the chamber, against which the pawl rests. Below the projecting point W is a spring, X, which has its upper end bent in a U-shaped form, the are of the bend extending over past the line of the slot R below the pawl S'.

`The seal Y is composed of a dat piece of metal having at one end-a square or rectangular hole, Y. This seal has stamped or impressed thereon the address or other direction, and in attaching said seal the bolt C is first drawn up, so as to clear the staple B. The hasp D is then placed over the said staple. After this is done the cross-limb Z of the seal is bent, as shown in Fig. I, and forced down into the slot R. In its course down the slot it first strikes the inclined surfaeeUof the pawl S and forces the pawl to the left. Directly below the pawl it strikes the arc-of the spring,` X, which is moved over into the opposite direction. Then the limb Z of the seal reaches the bottom of the slot, the upper edge ofthe limb passes the lower edge of the pawl, when the spring; V causes it to resume its normal, position. The are of the spring` X in the meantime rests against thelmb, as shown in Fig. llI. The bolt C is now moved down, which causes the pointed stem to pass through the cut-away portion T of the pawl. The curve forming the hook O strikes the limb and deects it to one side by bending it sullcently to permit said hook to pass below the limb, as shown in Fig. IV, when the limb Z will prevent thc bolt l'roln being withdrawn.

rIhe bolt may be provided with a vertical slot, a, at a point directly below the housing E, to receive any ordinary wire or tin seal, and the staple B has on one side an aperture, b, to which may be attached the usual padlock if it should at any time be found necessary to use either of these adjuncts.

Vhat we claim as new is In a seal-look, the bolt provided with ribs or feathers and with a locking or sealing slot, in combination with the staple B, the housing E, and the retainingspring F, and slot in the bolt for engaging with said spring, substantially as herein set forth.

In testimony that we claim the foregoing we have hereunto set our hands, this 28th day of April, 1887, in the presence of witnesses.
